Product Description 5 PRODUCT DESCRIPTION 5.1 General description The 2/2-way globe control valve Type 2012 is suitable for liquid and gaseous media. It uses neutral gases or air (control media) to control the flow of water, alcohol, oil, fuel, hydraulic fluid, saline solution, lye, organic solvent and steam (flow media). A particular feature of the globe control valves are screwed in seats which can be changed if required. 6 STRUCTURE AND FUNCTION 6.1 Structure The globe control valve consists of a pneumatically actuated piston actuator and a 2-way globe control valve body. The actuator is manufactured from PA or, for special operating conditions, from PPS. The self-adjusting packing gland ensures a high degree of tightness. The valve body, made of stainless steel, enables high flow values. 5.1.1 Restrictions WARNING! Risk of injury from water hammer! A water hammer could crack the lines and device. Due to the risk of water hammer, valves with a flow direction above seat must not be used for liquid media. Consider the type of flow direction and the type of medium for operation of the device.

Structure and Function 6.2 Function Depending on the version, the seat of the valve is closed with or against the medium flow. Spring force (CFA) or pneumatic pilot pressure (CFB and CFI) generates the closing force on the swivel plate. The force is transferred via a spindle which is connected to the actuator piston. 6.2.1 Control functions (CF) WARNING! For control function I Danger if pilot pressure fails. For control function I control and resetting occur pneumatically. If the pressure fails, no defined position is reached. To ensure a controlled restart, first pressurise the device with pilot pressure, then switch on the medium. 6.2.2 Flow direction below seat Depending on the version, the valve is closed against the medium flow with spring force (control function A, CFA) or with pilot pressure (control function B or I, CFB or CFI). As the medium pressure is under the swivel plate, this pressure contributes to the opening of the valve. WARNING! Medium may be discharged if minimum pilot pressure is too low or medium pressure too high. If the minimum pilot pressure is too low for CFB and CFI or the permitted medium pressure is exceeded, leaks may occur. Observe minimum pilot pressure. Do not exceed medium pressure. See chapter entitled 7.4.2 Pressure ranges.

Technical Data 6.2.3 Flow direction above seat The valve is closed by spring force (control function A, CFA) with the medium flow. As the medium pressure is over the swivel plate, it supports the closing process of the valve and also contributes to the sealing of the valve seat. The valve is opened by the pilot pressure. WARNING! Risk of injury from water hammer. A water hammer could crack the lines and device. Due to the risk of water hammer, valves with a flow direction above seat must not be used for liquid media. Consider the type of flow direction and the type of medium for operation of the device. 7 TECHNICAL DATA 7.1 Conformity The globe control valve Type 2012 conforms with the EU Directives according to the EU Declaration of Conformity. 7.2 Standards The applied standards, which verify conformity with the EU Directives, can be found on the EU-Type Examination Certificate and / or the EU Declaration of Conformity. 7.3 Type label To ensure complete opening, the minimum pilot pressure must be applied.
